PRESSURIZATION WAS NORMAL THE  WHOLE TIME. THE NOISE WAS CONSTANT MAKING IT VERY  DIFFICULT TO COMMUNICATE. RETURNED BACK TO MEM AND  ON DESCENT THROUGH 18000FT-16000FT THE NOISE  STOPPED.    AFTER FINDING THE NO 2 LH WINDOW PRESSURE SEAL TO  BE CUT.COMPLETED THE INSTALLATION OF THE NO 2 LH  WINDOW PRESSURE SEAL. SEALANT CURING  PERFORMED CABIN PRESSURIZATION CHECK REF B757 AMM  ABOVE.
